Chromosomal replication and the cell membrane
Current Opinion in Microbiology, 2005The importance of the cell membrane in bacterial chromosomal replication continues to emerge. Recent advances include better definition of the biochemical interaction between membrane acidic phospholipids and the replication initiator, DnaA protein, the physiological impact that an altered membrane lipid composition has on chromosomal replication and ...

Replication in Polytene Chromosomes
1972Replication of polytene chromosomes has been reviewed frequently in the last two decades, either as a facet of chromosome replication in general or in treatments restricted to polytene nuclei. The reader is referred especially to the following for further discussion and bibliographic references: Beermann (1962), Pelling (1969), Taylor (1969), Prescott (

Replication of Yeast Chromosomal DNA
Nature, 1974THE study of replication in higher eukaryotes has been hampered by the large size of the DNA molecules in their chromosomes. The yeast Saccharomyces cerevisiae is a eukaryote with very little DNA per haploid nucleus (9 × 109 daltons)1. This has facilitated measurement of intact yeast chromosomal DNA by sedimentation velocity2 and electron microscopy3 ...

A fractal model of chromosomes and chromosomal DNA replication
Journal of Theoretical Biology, 1989With the aim of clarifying topological problems involved in the process of chromosomal DNA replication, a fractal model of chromosomes was built based on the assumption that a part of a chromosome, e.g. a radial loop, is similar in shape to a whole chromosome and each radial loop represents structures in the lower-order organization (an assumption of ...

The haloarchaeal chromosome replication machinery
Biochemical Society Transactions, 2009The powerful combination of genetic and biochemical analysis has provided many key insights into the structure and function of the chromosomal DNA replication machineries of bacterial and eukaryotic cells. In contrast, in the archaea, biochemical studies have dominated, mainly due to the absence of efficient genetic systems for these organisms.

Replication of adenovirus mini-chromosomes
Journal of Molecular Biology, 1984We have isolated adenovirus origins of DNA replication from both the right and left ends of the genome, which are functional on linear autonomously replicating mini-chromosomes. The mini-chromosomes contain two cloned inverted adenovirus termini and require non-defective adenovirus as a helper.

The Dynamics of Chromosome Replication in Yeast
2003Publisher Summary This chapter deals with the dynamic aspects of chromosome replication in yeast and describes how the program of replication is laid down and carried out in Saccharomyces cerevisiae , with particular emphasis on the dynamic aspects of. It explains how the control of replication initiation is tied to phases of the cell cycle, how the

Studies of mammalian chromosome replication
Chromosoma, 1981Sister chromatids of metaphase chromosomes can be differentially stained if the cells have replicated their DNA semiconservatively for two cell cycles in a medium containing 5-bromodeoxyuridine (BrdU). When prematurely condensed chromosomes (PCC) are induced in cells during the second S phase after BrdU is added to the medium, the replicated chromosome

Replication of Protosomes and Chromosomes
1998• The replication of DNA is semiconservative, involving a single origin of replication in prokaryotes and multiple origins of replication in eukaryotes. • Synthesis of new DNA occurs by copying an existing template through the addition of 5′-nucleoside monophosphate units to the 3′OH moiety of a primer sequence.

Control of Chromosome Replication in Bacteria
1985The exciting progress that has recently been made in unravelling the replication control mechanisms that determine the copy numbers of several plasmids has been reviewed and updated by several contributors to this volume. In contrast, the control of chromosome replication in bacteria remains largely a closed book.
